摘　　要：结合云南省某市二级及以下沥青路面技术状况实测数据,采用差异性分析方法,对《公路技术状况评定标准》(JTG 5210—2018)中“公路技术状况检测与调查应按上行(桩号递增方向)和下行(桩号递减方向)两个方向分别实施,二、三、四级公路可不分上下行检测与调查”进行分析研究。结果表明:针对二级及以下沥青路面技术状况评定,特殊交通组成路段评定以单幅检测评定数据代替全幅检测评定数据有较大差异性;路网级的技术状况评定,随着检测总里程的增加,检测评定数据差异性弱化。This paper combines the actual measurement data of the technical condition of the asphalt pavement of a city in Yunnan Province,and adopts the method of variance analysis to analyze the technical condition assessment standard of highway( JTG 5210—2018),which states that "the inspection and investigation of the technical condition of highway shall be carried out in two directions:upward(the opposite direction of increasing pile number) and downward(the direction of decreasing pile number).The direction is implemented separately,and the second,third and fourth grade roads can be inspected and surveyed without dividing up and down rows".The results show that:for the technical condition assessment of asphalt pavement of grade 2 and below,the special traffic composition section assessment,the single width testing and assessment data instead of the full width testing and assessment data has a greater variability;the technical condition assessment of the road network level,with the increase of the total mileage of testing,testing and assessment data variability weakened.
